' To all whom t may concern,.-

Be it known that 1,. WILLIAM Il. BOUTELL, of Rochester, in the county'of Monroe andv State of New York, have inventedcertainnewand useful -Improvements in Paring and CoringMac-hines; and I dohereby declare the following to he a full, clear, and exact descripthe cam devi-ces for rotating the knife-carry? amiable operation ofthe knife; Fig. 9, a sec-- tion of the same, reference being had to the accompanying drawings, forming a part of,

this specification, and to the reference-numerals marked thereon.

My present invention relates to machines for paring and coring apples orsirnila'r fruit; and it has for its object toimprove theirconstruction and operation, whereby the construction is facilitated and the various movements and adjustments necessary to operate upon the fruit in the best manner are provided, all as will be hereinafterfullydescribed, the novelf features being pointed out in the claims at the end of this specification.

' In the accompanying drawings,`Figu1-e 1 is a front elevation of a paring and coring machine embodying my improvementwith a portion of the frame broken away; Fig. 2, a rear view of the same; Fig. 3, avertical sectional view on the line o, a of Fig. 1; Fig. 4, a seel.

Similary reference-numerals in the severa "figures indicate similar parts..l

1 indicates themain frame of the machine, of the usual or any preferred construction,

vprovided with suitable supporting-legs adapted for attachment to a base and having at its upper portion a removable rod or way 2,1`1`pon .which slides a movable carriage 3, supporting theparing audfcorin'g devces,'said carriage beingprovifded-at its upper end 1n the prcsent'instance witho apertures or eyes en#` the gear 8.

circling the rodor way 2, while itslower end operates inigu'ides 4 4 at the lower portion oli the frame', as shown. Mounted in suitable bearings formed in the main frame is a stud- Vshaft carrying a large gear 5, to which is ati tached an operating-hand1e 6 and also a loew` eled` pinion 7, meshing with corresponding teeth onA a large operating-wheel S. This wheel `8 extends in a plane parallel with that of the main frame, being journale'd on an arbor` or pin 9, mounted on the main frame,

and is provided with a small mutilated pinion 10, Vadapted to mesh withashort rack 11,

`located on the rear sideofthe carriage 3 and' above and below thecenter of rotation of This arrangement of the camsurfaces 'upon opposite sides of the Icenter "of rotation permitsthem to operate conjointly with the rack and pinion to aiitect the lvariations of speed in the carriage. The segmen 11 is engaged by the pinion 10, and thev movement. in the `same direction continues at a decreased speed until the latter partsr Vare disengaged and the carriage is returnedrto" its normal position by the action ol ,the rib 12 on the lower 4cam-surface 4lat. it will be noticed that the rib 12 is continuous between `revolved a distance equal" to the length of the rib, thereby arresting the movement of the carriage suiiiciently to allow the operator ample opportunity to apply the `fruit tothe fork without interfering' withthe constant rotation of the drivingr mechanism.`

l5 indicates the hollow fork-shaftphaving atoneend the fruit-fork 16 and at the other `a` pinion 17, meshing with the operating-gear 5, 'and 18 indicates the usual coredoffer, passing longitudinally through said `fork-shaft and operated in a directionto eject the core from theforlc by meansof the bell-crank lever li),

tal rib 12 first engages the calnsurface 13, sliding the carriage inwardly untiithe rack` plvoted at 2.0 to the main frame and having one of its arms in position to be operated upon by a stud or projection 2l on the main gear 8, as shown in vli`ig.'2. As a means for supporting the fork-shaft, attaching it tothe frame, and at the same time providing for such adjustment as may be necessary to take up wear of the parts, I mount said shaft in a long bearingsleeve 22, having the lugs or feet 23 at the ends, said sleeve being split at the ends from;l the upper side downward and nearly through the lugs 23, as shown'in Fig.

3, and through these split portions Ipass bolts 24, having nuts on their outer ends, as shown. This construction provides for attaching the bearing-sleeve to the main frame and also provides for the necessary adjustment to take up the wear at the ends of the sleeve by the adjustments of the nuts on the scouring-bolts 24, thereby materially simplb' tying the parts and reducing the number of castings. I prefer that the bearing-sleeve be cored ont at the center-,so that thek only bearing portions that engage the shaft will be near the extremeends of the split portions.

I` find that it is desirable in machines of.

this description thatv when the carriage is moved in a direction to cause the coperation ofthe paring devices with the fruit on the forkishaft the' first portion of said motion be comparatively rapid to bring the knife into engagement with the fruit, then thatV the paring operation be accomplished at an even and slower speed, and that the return or outward movement of the carriage be considerably more rapid than the inward movement, and in the present machine this is caused by the instrumentalities employed, the coperation ofthe cani 12 with the surface 13 on they carriage moving the latter rapidly and until the rack 1l and pinion 10 engage, then the comparatively slow movement caused by the rack and pinion, which have a considerably smaller radius than the cam 12, completes the paring and coring operations, then the rapid outward movement of the carriage caused by the engagement of the cam 12 with the surface 14. The 3am 12, it will be noted, is long enough to contact with both the surfaces 13 and 14 on the carriage, so that when in the position shown in Figs. land 2 it will lock the latter at the outer extreme of its movement, and also that the carriage is held stationary while the wheel is rotatinga distance equal to the `length of the cam' 12thereby allowing time for the application of the fruit to the fork without arresting the operation of the handle.

Mounted upon the stud or arbor 25, secured to the carriage, is the rocking head 26, carrying the paring-knife andzoperating parts, em-A bodying the sleeve portion, andcapable of a rotary movement on the stud25 andhaving bearings lextending at right angles to said the rotary arbor 27, having the oscillatoryhead carrying the paring-knife.

The paring-head embodiesv paring-knife 3l at its iower end. ne lower end of 'the head is provided with the ont wardly-extending arm having the slot for the passage of the knife-arm 30 and Serfy rated on its under side for the engagement of the end of the spring 34, the upper end .of said spring engaging the arm 29 for the pur pose of keeping the knife pressed toward the center of the paring-head. The rocking head 26 is further provided with a shoe 35, adapted whenthe carriage is moved toward the fruitfork to cooperate' with the under side of the way or rib 3 6, formed on the main frame, as shown in Figs. l and 4. For the purpose of operating the rocking head 26 `tomovethe paring-knife into and ont of contact with the fruit l provide it on its rear side with a nintilated pinion 37, adapted to engage with a corresponding rack 88, formed on the main frame, said pinion in the present instance embodying but two teeth, as shown in Fig.

The rotation of the paring-head carrying the edto cooperate with a recess 40, formed in the `main frame, and beneath and at opposite sides of said tooth or projection I arrange two hook-shaped projections or teeth 4l and 42, cooperating with corresponding shoulders or lugs 43 and .44, arranged at the sides of and beneath the recess 40, as shown particulariy in Fig. 8. Said teeth or projections 41 and 42 are shorter and nearer to the center of rotation of the spindle 27 than the tooth 39, so that as the carriage moves inward toward the fork .the side of the tooth 39 will engage ways or bearing-surfaces S0, formed upon the frame on-one side of the recess't.

Thentie tooth 41, engaging the projection 43, will turn the head quite rapidly until the eiongated tooth 39 enters the recess 40. As the engagingiine of the tooth 39 and the sides ofthe recess 40 are farther removed fromthe center of rotation, the rotary movement of the head will be slower until the tooth 39 is operated upon by the inner side 40X of the recess 4G, which is nearer the center ot rotation, and the head is caused to rotate more rapidiy again until the side of the tooth 39coperates with the surface 80 on the main frame and the paring-knife moves parallel with theorlr and away from the fruit. The first portion of the movementof the head in each direc tion is caused more rapidly by the engagement of the teeth 41 and 42 and lugs 43 and 44, the inward and reverse movements being plainly shown in dotted lines in This varying `movement is particularly advantageous ina machine-of this kind, as it prevents the repairing of the ends ofv the fruit, the knife moving morequickly at the eze tremes or shorter circumference of the fruit. The shape and manner of coperationof the 'urved projections 4l and 42 with theprojections or surfaces 43 and 44 and the projection 39, operatingin the recess 40,are advantageous whether or not the relative lengths of these parts are as shown and described in that the wear upon this portion ot the machine which is subjected to the corroding action ot the fruit juices is materially decreased or is decreased to such an extent that the parts will not wear sufficiently to become loose. This result is obtained by reason of the factthat the projections 41 and 42 havetheir engaging faces curved to substantially the curves ot the ends of the projections 43 and 44, so that a broad wearing-surface is afforded and the parts are not merely in point-contact, as is the case, for instance, with such a machine as that shown in my reissued patent, No. 11,798. `As the carriage moves outward the rocking headis tilted to the position shown in Fig. 1 by the rengagement ot the pinion 37and rack 38, the shoe 35 having moved ott the bearing-surface 36 on the main frame.

In order to properly limit the rocking motion of the rocking head carrying the paring devices, I provide the sleeve 26 with a stoparm 54, adapted to coperate with the head of an adjustable stop in the form of a bolt 55,V passing through and adjustable in a yslot 56, formed'in the carriage, as shown in Figs. 1, 2, and 6.

50 indicates the flotter-arm, adjustably secured to the outer end of the carriage by bolts 51 and 53, the latter passing through a perforation in the carriage and through a segmental slot 52 on the arm, whereby by loosening the nut on the bolt 53 the arm may be adjusted on the bolt 51 as a pivot, this construction providing means whereby the doffer and the corer mounted thereon may be adjusted with relation to the fork and rigidly secured in position. The arm 50 is provided with a stud 57, on which is mounted an oscillating corer-head 58, having an arm 59, with a shoe at the end thereof arranged to coperate when the carriage is moved inward with abearing-surface 60, formed on the lower side ot' a bracket 63, adjustablysecured to the main frame by the bolts 64 ou the main frame operating in slots in the bracket, as shown in Figs. 1 and 7. The Colfer-head 58 is also provided with a mutilated pinion 6l, (embodying two teeth in the presentinstance,) engaging with teeth 62, formed upon the under side of the bracket 63, for causing the oscillation of said head on the stud 57 when the carriage is near the outer end of the frame, as in Figs. 1 and 7. The coring knife or tube 65 is adjustably secured to the arm 66, bolted to an extension of the head, said tube being ot any approved construction and forming no portion of my present invention.

The operation ot the coring device will now be understood. As the carriage moves inward the rack 62 on the frame causes the downward movement ot' the corer-head until the coi-er is in line with the fork. Then the shoe on the arm 59, engaging the surface 60, maintains it in this position during the inward movement to core the fruit and remove it from the fork, and as the carriage moves outward again the pinion 6l and rack 62 engage and cause the corer-head to move up to the position shown, the dofter-arm 50 engaging the outer side of the fruit and causing its removal from the corer in the usual manner.

The various adjustments permitted the bearing for the fork-shaft and the dotlt'er-arm and its connected parts enables me to take up any lost motion due to the wear of the parts and also to cause the proper alinement of the coring-tube and fork-shaft.
